Unlocking the secrets of the Subaru key can be a daunting task, but don’t worry – we’re here to help.

Understanding Your Subaru Key

Your Subaru key is an essential component of your vehicle. It allows you to gain access to your car, lock and unlock doors, and activate the panic alarm system. To better understand your Subaru key, let’s take a closer look at its components and functions.

The Components of Your Subaru Key

Your Subaru key is made up of three fundamental components: the key blade, remote transmitter, and the emergency key. Understanding each part’s function will help you to appreciate how they work together to keep your vehicle secure.

  • The Key Blade: The key blade is a flat, metal part that is used to physically unlock the car door. It is inserted into the lock on the door handle or the ignition and turned to open or start your vehicle.
  • The Remote Transmitter: The remote transmitter is a small, handheld device that lets you control your car’s locks without inserting the key blade. It has several buttons that can be used to lock or unlock the doors, pop the trunk, activate the panic alarm, or start the vehicle remotely.
  • The Emergency Key: The emergency key is a small, metal key that is hidden inside the remote transmitter. It can be used to physically unlock the car door if the battery dies, and the remote is not working.

Now that we have a better understanding of the components let us explore their functions.

The Functions of Your Subaru Key Components

Your Subaru key components have specific functions that depend on their design and functionality. Here is a breakdown of each component’s role:

  • The Key Blade: The key blade is essential in unlocking the car door or starting the ignition. It can be inserted into the keyhole directly for use, or through a switchblade technology that hides the blade inside the remote transmitter.
  • The Remote Transmitter: The remote transmitter allows you to control the car’s keyless entry system for locking and unlocking the doors, rear hatch, and activating/deactivating the panic alarm. Additionally, if you have Subaru’s advanced feature, you can use the remote to start the vehicle and control other functionalities of the car.
  • The Emergency Key: The emergency key can be used to manually unlock the car door if the battery is dead or the remote transmitter is faulty. You can access the emergency key by pushing the button on the remote transmitter that releases the blade.

Programming Your Subaru Key

If you lose or damage your Subaru key, you’ll need to replace it to continue using the keyless entry and ignition functions. Fortunately, programming a new Subaru key is relatively easy. You can have a new key programmed at a dealership or hire a professional automotive locksmith who specializes in Subaru key programming.

The cost of programming a new Subaru key varies, but it’s always cheaper than getting a replacement transponder key, which requires additional programming and reprogramming of the car’s system.

Now that you understand your Subaru key’s components, function, and how to program it let us ensure you keep it in safe place, so why not invest in a keychain or key holder that can keep your Subaru keys organized and prevent them from getting lost or damaged.

When to Replace Your Subaru Key

As one of the most important components of your vehicle, your Subaru key is responsible for providing access to your car and starting the engine. However, like any other part, the key can wear down or stop working properly over time. In this article, we’ll explore the situations where you may need to replace your Subaru key.

Worn Out Key

If you’ve been using the same key for several years, you may start to notice signs of wear and tear. A worn-out key may no longer function as it should, making it difficult or impossible to turn the ignition. In some cases, the key may break off in the lock or become stuck, causing further problems. If you notice any of these signs, it may be time to consider replacing your Subaru key.

Keep in mind that a worn-out key can also put a strain on your ignition, causing it to malfunction over time. This can lead to costly repairs down the line, so it’s important to address the issue as soon as possible.

Lost or Stolen Key

If your Subaru key has been lost or stolen, it’s crucial to replace it right away. Not only does this prevent unauthorized access to your vehicle, but it also ensures that your keyless entry system works properly. Without a working key, you may have trouble entering your car or starting the engine, and you may even be stranded in an emergency situation.

Replacing a lost or stolen key can be a bit more complicated than simply buying a new one. In most cases, you’ll need to have your key reprogrammed to match your vehicle’s security system. This process typically involves visiting a dealership or locksmith, who can create a new key using specialized tools and software.

Key Battery Replacement

If your remote transmitter stops working, it may be due to a dead battery. Fortunately, replacing the battery can be done easily and inexpensively at home with a new battery and some basic tools. Keep in mind that the type of battery you need may vary depending on your specific year and model of Subaru.

To replace the battery, you’ll first need to open the remote transmitter using a small screwdriver or coin. Once inside, you can remove the old battery and replace it with a new one. Be sure to handle the battery carefully and dispose of it properly, as it contains hazardous materials.


If you’re experiencing any issues with your Subaru key, it’s important to address them promptly to avoid further damage or inconvenience. In some cases, a simple battery replacement may be all that’s needed, while in others, a full key replacement may be necessary. Whatever the situation, working with a trusted dealership or locksmith can help ensure that your key is functioning properly and providing reliable access to your vehicle.
